Hidden wedges are spectacular. They give the allusion of wearing a flat while still adding height and tone to the leg- perfect when wearing a romper. Best of all, they are comfortable to walk in. This may be fashion's best kept secret, as they are not easy to find.

(Note: any hidden wedges by 80%20 are amazing, although it is difficult to find retailers in this area. I use http://www.8020nyc.com/ to find styles first, and then the site will direct you to online retailers where you can purchase.)
